Throughout the years we've seen many different marriage proposals in video-games, but I don't think a single one has been quite as heartwarming and straight up badass as this one.

Eventually the project actually gained the attention of Valve who gave Gary's custom level the ultimate touch: Ellie McLain, better known as Glados.

Check out a video run-through of the level below, or download the level and try it for yourself.
